MACHINE FOR HOIS'IING HAY, 8w.

Specification forming; part of Letters Patent No. 27,994, datedApri1'24, 1860; Reissued September To all whom it may concern:

Be it known that I, JOHN S. LLOYD, of

Salem, in the county of Salem and State of New Jersey, have invented anew and useful improvement in machinery for elevating or hoisting hay,grain, coal, sand, marl, or other material and depositing the same inany place desired; and I do hereby declare thatthe following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification.

Figure 1 is a perspective view of the machinery as seen in operation, inwhich A represents an inclined single rail railway, attached to therafters of a barn or other building near the peak, or to a frameoverhead, by framework shown at B in Fig. 3.

On the upper side of this rail is a groove or gutter in which the wheelsB, B, attached to the blocks D, D, move to convey the hay, grain orother material to or over any part of the barn or other place required.Upon the axles of these wheels, are placed the arms C, O, which connecttogether at the bottom and form part of, or are firmly secured to theside of the upper double block D. Upon the upper part or top of thisblock are firmly fastened the two arms E, E, which terminate in loops towhich are attached the ropes G, G, the forward one of which passesaround the pulleys in the blocks D, D, under the railway A, to theopposite end of the building or frame, over the upper pulley I and underthe lower pulley I, to the swingle tree L, to which the horse isharnessed. The rope attached to the other arm E, )asses over the pulleyI, at the lower end of the railway, and is fastened to the weight W, topull back the wheels B, B, after the fork or bucket has discharged itsload. To the lower block D is attached the fork F, by means of a jointor hinge, which allows it to move forward freely. The fork is kept toits place and prevented from discharging prematurely by a bolt or slideK placed upon the handle or shank of the fork, and confined to REISSUEHits place by loops or clasps, which allow it to have a slight motionalong the shank. The head of this slide is beveled upon one side, and onthe other is fitted into a notch n, in the lower end of the lower blockD. A spring .9 placed either in the handle or head of the fork keeps theslide in its place.

To the lower end of the slide a rope or cord is attached, by means ofwhich the slide can be drawn from the notch n, and the load dischargedat any given point.

The lower or outer end of the railway A, is supported by a stout'ironstrap H, one

railway, and the other end is firmly bolted to the rafters at the apex.here the machinery is used in a frame instead of a building, the lowerend of the railway should be supported by a post firmly placed on theground instead of this strap. At the opposite end of the building orframe are two pulleys I, I, placed nearly under the railway. The rope Grpasses over the upper pulley, which is near the railway perpendicularlydown, under the lower pulley, which is placed near the ground to theswingle tree L to which the horse is attached. Immediately in front ofthis, and at half the distance from it required to be traversed by thehorse in raising the weight, a stout box is sunk in the ground intowhich the bottom of the post P is fitted. By this ar rangement the postcan be readily taken away when not in use. The back part of this post isbeveled toward the top, so that the rope in passing around it is throwninto the groove of the pulley I placed on the upper end of the lever'R,which works in a hollow in the upper end of the post P to which it isattached by a pin or 'bolt upon which it turns forward. The outer partof the lower end of this lever is beveled, and the inner part is notchedat n, so as: to fit against the front of the upper part of the slide K,which is attached to the front of the post P, by clasps which allow itto work perpendicularly. The head of this slide is end of which isfastened to the end of the.

beveled on the inside. When the slide is'in' its proper position, thehead or upper end of it fits into the notch n, in the lever B, andprevents the bottom of it from moving inward. It is kept to its place bya spring S which passes through the post at 39 into a notch or hole inthe slide. This spring is kept to its place by a wedge half its lengthinserted in the post P, beneath it, and made to fit tightly. A rope f isattached to the lower end of the slide, and passes under the pulley I,placed in front of the post near the bottom, by means of which the slideK is drawn down, and the head of the lever B allowed to move forward andliberate the rope G without having to back the horse.

A broad band Z2 passes around the back and sides of the upper part ofthe post P, which serves the double purpose of strengthening the postand furnishing a firm support for the pin or bolt upon which the lever Bturns.

Fig. 2 represents a back and lateral view of the fork F, blocks D D,slide K, joint J, notch n, and cord 9.

In Fig. 3, A, represents the end of the barn, and B the method, by whichthe railway with the rafters of the building or with a frame, so as toallow the wheels B, B, Fig. 1 to work upon the railway free from allobstruction.

Fig. 4 represents a self adjusting bucket A upon the sides of which areplaced obliquely two pieces of wood or metal as shown by B, the upperpart of which terminates in cars or bales for receiving the handle orbale of the bucket, and the lower part supporting the hinge g at thelower corner. These pieces are placed opposite and so firmly attached tothe bucket as to sustain its weight when filled. The bottom of thebucket is movable and is designed to turn upon the hinge g to which itis attached at one end. The other end rests upon the notch 17,, in thespring f. Upon the under side of this bottom, and connected with it bythe clasps or loops 6, e, is a slide C, which passes a short distancebeyond the bucket, at the back part, and terminates at the other end, ina large oblong head d, which is beveled on the upper side. When in itsnatural position the under part of this head projects below the bottomof the spring and on a line with the inner surface of the bucket. Thespring f is firmly fastened upon the front of the bucket, in such amanner that when in a state of rest, the notch n, passes under the frontpart of the movable bottom and supports it in its place. When ready tobe discharged the projecting part of the slide C, strikes against a postor other firm substance and is driven forward against the lower part ofthe spring f driving it off and forcing the notch 92, from under thebottom, when the pressure of the materials within the bucket pressesopen the bottom and effects a discharge. When the bucket again descendsto the ground the projecting head of the slide first strikes and forcesthe bucket into its proper position on the notch 'It.

D, D, represents the strap by which the block is fastened, and also thehook which connects to the handle or bale of the bucket.

Fig. 5 represents an ordinary scoop which is merely designed to be setupon the fingers of the fork F, Fig. 1, and secured to its place byscrews passing through its head into the shank of the fork.

Operation: In unloadin hay, the fork F is dropped upon the load standinunder the lower end of the railway, and fil ed with hay by pressing thefingers of the fork into the load or otherwise. The horse attached tothe rope G at L is then started forward, drawing up the fork F until theblocks D, D, come together, when the wheels B, B, are drawn forward upthe inclined railway, carrying along the fork and hay. When at thedesired oint, the rope g, attached to the slide K 1n the fork F, ispulled, when the fingers of the fork turn, and the hay slips off, by itsown weight. In drawing up the fork or bucket the horse passes around thepost P and returns to the place of starting. Then the contents of thefork or bucket are discharged, the cord attached to the slide in thepost P is pu led, and the rope G, which had passed around the post, andguided by the beveled back into the groove of the pulley I at the top ofthe post, draws the upper end of the lever B forward allowing the ropeto pass out of the groove in the pulley and become slack, when theweight W draws the wheels B B, down the inclined railway to the lowerend of it when the fork F again drops upon the load by its own weight.The lower end of the lever B being heavier than the upper, it returns toits proper position when released from the rope, by passing over thebeveled head of the spring 8 and forcing it downward either by its ownforce, or that of a person, until the spring again moves up into thenotch n. By holding the spring down by the cord f until the lever hadfallen back to its place, the result would be most readily accomplished.

The mode of operatin the machinery being so nearly the same or all kindsof material a further description of the mode of operating is deemedunnecessary.

I do not claim the invention of blocks, pulleys, forks or railways forraising hay or other material, but

What I do claim and desire to secure by Letters Patent is 1. Theconstruction, combination and arrangement of the fork, bucket, cords,levers,

pulleys, sprin%s and railway, the arms E E 2. I also claim the post P,as constructed to the block and the mode of attaching in combinationwith the pulley, lever, slide, and supporting the railway t0 the barn orspring and cord.
